Correct Answer: D

Rationale: Fat-soluble vitamin D and calcium are necessary in adequate amounts to prevent rickets. No correlation exists between rickets and folic acid, iron, or vitamins A and C.

Correct Answer: A

Rationale: Many foods interfere with iron absorption and should be avoided when iron is consumed. These foods include phosphates found in milk, phytates found in cereals, and oxalates found in many vegetables. Vitamin C-containing juices enhance the absorption of iron. Multivitamins may contain iron; no contraindication exists to taking the two together. Meat, fish, and poultry do not affect absorption.

Correct Answer: D

Rationale: Deficiencies can occur when various substances in the diet interact with minerals. For example, iron, zinc, and calcium can form insoluble complexes with phytates or oxalates (substances found in plant proteins), which impair the bioavailability of the mineral. This type of interaction is important in vegetarian diets because plant foods such as soy are high in phytates. Fat and vitamins C and A are readily available from vegetable sources. Plant proteins are available.

Correct Answer: C

Rationale: Pure vegetarian (vegan) diets eliminate any food of animal origin, including milk and eggs. These diets require supplementation with many vitamins, especially vitamin B6, vitamin B12, riboflavin, vitamin D, iron, and zinc. Niacin, folic acid, and vitamins C and E are readily obtainable from foods of vegetable origin.

Correct Answer: C
